  • FIG. 1 is a diagram illustrating two process stages for computer graphics with out-of-band (OOB) background. OOB background comprising one or more 2D OOB background images is not included in typical specifications for 3D graphics rendering. It is to be understood that conventional computer graphics engines generate 2D display images by only rendering 3D entities. In a loading stage 11, information regarding OOB is provided, and an OOB background image is generated or acquired according to the provided information and is stored in memory for subsequent rendering. The OOB background image may comfort to the portable network graphics (PNG), graphics interchange format (GIF), or JPEG specification, or others. In a rendering stage 13, the OOB background image is retrieved from the memory and is duplicated in a frame buffer, and subsequently, a foreground image is generated by rendering 3D entities and is stored in the frame buffer to form a display image. FIG. 2 is a diagram illustrating generation of a display image with reference to the described stages. In the loading stage 11, information regarding OOB background is provided, and an OOB background image IMG210 illustrating a scene of an ice field is accordingly generated and stored in memory as an OOB background image. In the rendering stage 13, the OOB background image 210 is retrieved and duplicated in a frame buffer, and subsequently, a foreground image IMG230 illustrating a standing penguin is generated by rendering 3D entities, and is insert into the OOB background image IMG210 of the frame buffer to form a display image IMG250 illustrating a penguin standing on the ice field.
  • FIG. 3 is a diagram of an embodiment of a system for computer graphics with OOB background employed in the loading stage 11 (FIG. 1), comprising a loading unit 31, a scene graph renderer 33, a storage device 35, memory 37, and a frame buffer 39. The storage device 35 may be a hard drive, magnetic drive, optical drive, portable drive, or nonvolatile memory drive. The storage device 35 and associated computer-readable media thereof (if required) provide nonvolatile storage of a 3D rendering file utilized in 3D graphics rendering. The 3D rendering file describes information regarding OOB background, 3D entities, texture images for applying to 3D entities, or others. The memory 37 may be dynamic random access memory (RAM), synchronous dynamic random access memory (SDRAM), static random access memory (SRAM), or others, and provides volatile storage of one or more OOB background images and foreground images. The frame buffer 39 holds a frame of data for outputting to a display device, such as a supertwisted nematic liquid-crystal display (STN-LCD), a thin film transistor liquid-crystal display (TFT-LCD), an organic light emitting device (OLED), and the similar. The frame buffer size is typically the size of the maximum image that can be displayed on the display device. The frame buffer 37 holds a display image while the display image is being “painted” on the display device. Details of the loading unit 31 and the scene graph renderer 33 are described in the following paragraphs, and briefly described herein.
  • FIG. 4 is a flowchart illustrating an embodiment of a method for computer graphics with OOB background, employed by the loading unit 31 (FIG. 3) during the loading stage 11 (FIG. 1). In step S411, a 3D rendering file is acquired from the storage device 35 (FIG. 3), and the acquired file is stored in the memory 37 (FIG. 3). FIG. 5 is a diagram illustrating the data structure of an embodiment of a 3D rendering file 5100. A OOB background area of the 3D rendering file 5100 further comprises ten fields: 3D object structure 5111; color RGBA of 4 bytes 5113; mode of 1 byte 5115; filename of a string 5117; image type of 1 byte 5131; image width of 4 bytes 5133; image height of 4 bytes 5135; image size of 4 bytes 5137; image data offset of 4 bytes 5139; and image data of a byte array 5151. The 3D object structure field 5111 provides an object type property containing a value “OOB-background” indicating that this 3D object is related to OOB background. The OOB background field may describe OOB background with a single color value, such as “red”, “blue”, “pink”, and the similar, one or more OOB background images, or an external link to an image file, such as “.png”, “.gif”, “.jpg”, and the similar. When describing OOB background image with a single color value, the mode field 5115 records information indicating internal OOB background, and the color RGBA field 5113 records the specific color value. When describing OOB background image with one or more OOB background images, the mode field 5115 records information indicating internal OOB background, the image type, width, height and size fields 5131 to 5137 record profile data of one or more OOB images, and the image data field 5151 records actual image data. When describing OOB background image with an external link to an image file, the mode field 5115 records information indicating external OOB image, and the filename field 5117 records a filename of an image file storing OOB background.
  • Referring to FIG. 4, in step S431, it is determined whether the acquired 3D rendering file comprising information indicating that OOB background is employed. The determination may be achieved by inspecting whether a value of an object type property is “OOB_background”. If so, the process proceeds to step S433, otherwise, to step S471. In step S471, the loading unit 31 (FIG. 3) informs the scene graph renderer 33 (FIG. 3) of that clearing of the frame buffer 39 (FIG. 3) is required. The loading unit 31 may modify a clear flag 371 (FIG. 3) with “true” to indicate clearing of the frame buffer 39. Thereafter, the scene graph renderer 33 clears the frame buffer 39 when detecting that the clear flag 371 is “true”. In step S433, it is determined whether one or more OOB background images are stored in an image file of the storage device 35 (FIG. 3), or the memory 37. The determination may be achieved by inspecting whether the mode field 5115 (FIG. 5) records information indicating internal or external OOB background. It is determined that one or more OOB background images are stored in an image file when the mode field 5115 (FIG. 5) records information indicating external OOB background, and the image data field 5151 records actual image data. It is determined that one or more OOB background images are stored in memory when the mode field 5115 (FIG. 5) records information indicating internal OOB background. The process proceeds to step S437 when the OOB background image/images is/are stored in an image file, otherwise, to step S435. In step S435, an OOB data pointer is assigned to point an address of the beginning of a region storing the OOB background image/images for subsequent OOB background image acquisition. In an embodiment, an OOB data pointer is assigned to point an address of the beginning of the image data field 5151 (FIG. 5) of the memory 37. In another embodiment, an OOB data pointer is assigned to point a begin address of a region of read only memory (ROM), storing one or more OOB background images. In step S437, one or more OOB background images are retrieved from the image file according to the content of the filename field 5117 (FIG. 5), the retrieved OOB image/images is/are stored in the memory 37, and an OOB data pointer is assigned to point an address of the memory 37, indicating the beginning of a region storing the newly retrieved OOB background image/images, for subsequent OOB background image acquisition. In step S451, one or more OOB background images are acquired according to the OOB data pointer and are processed if necessary. The OOB background image/images may be enlarged or reduced to fit the storage space of the frame buffer 39 (FIG. 3). The OOB background image/images may be decompressed when OOB background image/images is/are in a compress format, such as JPEG, and the similar. In step S453, the loading unit 31 informs the scene graph renderer 33 of that clearing of the frame buffer 39 is not required. The loading unit 31 may modify a clear flag 371 (FIG. 3) with “false” to indicate no clearing of the frame buffer 39. Note that the OOB background image is not generated by rendering any 3D entities with the scene graph renderer 33.
  • FIG. 6 is a diagram of an embodiment of a system for computer graphics with OOB background employed in the rendering stage 13 (FIG. 1), comprising the scene graph renderer 33, the memory 37, the frame buffer 39, a display controller 61, and a display device 63. The memory 37 further stores data of 3D entities 375, such as triangles, polygons, rectangles, or others. The display controller 61 directs the display device 63, such as a STN-LCD, a TFT-LCD, an OLED display, and the similar, to display the content of the frame buffer 39. Details of the scene graph renderer 33 are described in the following paragraphs, and briefly described herein.
  • FIG. 7 is a flowchart illustrating an embodiment of a method for computer graphics with OOB background, employed by the scene graph renderer 33 (FIG. 6) during the rendering stage 13 (FIG. 1). Note that this embodiment is employed in a hardware environment comprising single frame buffer. In step S711, it is determined whether OOB background is required during 3D graphics rendering. The determination may be achieved by inspecting the clear flag 371. It is determined that OOB background is required when the clear flag 371 is “false”. It is determined that OOB background is not required when the clear flag 371 is “true”. If so, the process proceeds to step S731, otherwise, to step S751. In step S751, the frame buffer 39 (FIG. 6) is cleared to avoid the intervention of a previous display image. In step S731, it is determined whether OOB background comprises multiple animated OOB background images. The determination may be achieved by inspecting whether the image type field 5131 (FIG. 5) stores information regarding an animated image file, such as a GIF file, and the similar, determining a quantity of the animated OOB background images according to values of image width, height and size fields 5133 to 5137 (FIG. 5). FIG. 8 is a diagram illustrating embodiments of animated OOB background images IMG810 to IMG850. The animated OOB background images are sequentially and cyclically duplicated in the frame buffer 39. That is, at a particular time, one of animated OOB background images is selected and duplicated in the frame buffer 39, as a current OOB background image. In step S733, one of the animated OOB background images is determined as an OOB background image to be duplicated according to current time. In step S735, the determined OOB background image is duplicated in the frame buffer 39. In step S771, a foreground image is generated by rendering 3D entities 375 (FIG. 6) and is stored in the frame buffer 37. It is to be understood that a portion of the stored OOB background image may be overwritten with all or a portion of the generated foreground image, or all or a portion of the stored background image may be blended in a portion of the stored OOB background image in order to form a display image to be outputted to the display device 63. Those skilled in the art may perform well-known methods, such as vertex processing, clipping, primitive assembly, triangle setup, rasterization, occlusion culling, parameter interpolation, pixel shader, or others, to render 3D entities 375. In some embodiments, operations of step S451 (FIG. 4) during the loading stage may be omitted, and these omitted operations may be executed between steps S733 and S735 during the rendering stage if necessary.
  • FIG. 9 is a diagram of an embodiment of a system for computer graphics with OOB background employed in the rendering stage 13 (FIG. 1), comprising the scene graph renderer 33, the memory 37, first and second layer frame buffers 91 a and 91 b, a display controller 93, and a display device 95. The memory 37 further stores data of 3D entities 375, such as triangles, polygons, rectangles, or others. The first layer frame buffer 91 a holds an OOB background image, and the second layer frame buffer 91 b holds an OOB foreground image for outputting to the display device 95, such as a supertwisted nematic liquid-crystal display (STN-LCD), a thin film transistor liquid-crystal display (TFT-LCD), and the similar. Sizes of both the first and second layer frame buffer 91 a and 91 b are typically the size of the maximum image that can be displayed on the display device 95. The first and second layer frame buffer 91 a and 91 b hold OOB background and foreground images while a corresponding display image is being “painted” on the display device 95 via the display controller 93. Details of the scene graph renderer 33 are described in the following paragraphs, and briefly described herein.
  • FIG. 10 is a flowchart illustrating an embodiment of a method for computer graphics with OOB background, employed by the scene graph renderer 33 (FIG. 9) during the rendering stage 13 (FIG. 1). Note that this embodiment is employed in a hardware environment comprising two layer frame buffers. In step S1011, it is determined whether OOB background is required during 3D graphics rendering. The determination may be achieved by inspecting the clear flag 371. Detailed examples of the determination may follow the description of step S711 (FIG. 7). If so, the process proceeds to step S1031, otherwise, to step S1051. In step S1051, the first layer frame buffer 91 a (FIG. 9) is cleared to avoid the intervention of a previous background image. In step S1031, it is determined whether OOB background comprises multiple animated OOB background images. Detailed examples of the determination may follow the description of step S731 (FIG. 7). In step S1033, one of the animated OOB background images is determined as an OOB background image to be duplicated according to current time. In step S1035, the determined OOB background image is duplicated in the first layer frame buffer 91 a. In step S1071, a foreground image is generated by rendering 3D entities 375 (FIG. 9) and is stored in the second layer frame buffer 91 b (FIG. 9). Those skilled in the art may perform well-known methods, such as vertex processing, clipping, primitive assembly, triangle setup, rasterization, occlusion culling, parameter interpolation, pixel shader, or others, to render 3D entities 375. It is to be understood that the display controller 93 may overwrite a portion of the OOB background image from the first layer frame buffer 91 a with all or a portion of the foreground image from the second layer frame buffer 91 b, or blend all or a portion of the foreground image from the second layer frame buffer 91 b in a portion of the OOB background image from the first layer frame buffer 91 a when both layer frame buffers 91 a and 91 b hold images to be displayed. It is to be understood that the display controller 93 may directly output the foreground image from the second layer frame buffer 91 b to the display device 95 when only second layer frame buffer 91 b holds an image to be displayed. In some embodiments, operations of step S451 (FIG. 4) during the loading stage may be omitted, and these omitted operations may be executed between steps S1033 and S1035 during the rendering stage if necessary. Those skilled in the art will recognize that the disclosed OOB background images, the generated foreground images and display images are 2D bitmapped images.
